I never got snappies of him DOING it ...
But dear ole Boots, da Kat, was rather skilled at turning ON the bathroom sink
when the desire for a 'fresh sippa wadder' crossed his furry brow.

The bathroom faucet was a single-lever temp and flow controll type ...
dunno what his method of operation was - but he could sure turn it ON
when he felt the need.

I *panicked* more than a few times when I'd enter the basement, hear a noise ...
then realize that it was WATER RUNNING upstairs!
A couple time he *bumped* the lever toward the HOT side ... those days
it took an hour or so before the hot water heater 'recovered' and managed
to produce hot water again.

Miss ya, Boots!
